Quality of life and long-term results in patients operated on for Esophageal Atresia.

Background: Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) represents the most severe entity among the foregut malformations, with patients at risk of chronic morbidity. This study aims to investigate on health-related quality of life (QoL) and long-term results in patients with EA.
Methods: 50 patients (30M, 20F, mean age: 14-year-old), among 82 patients operated from January 1995 to December 2005, answered the questionnaire. Two groups where compared: 8-12 years (A), 12-18 years (B). The survey investigated on 5 itmes: dysphagia; GERD; pulmonary affections (asthma, bronchitis, episodes of chronic cough during a year); growth and nutritional status (BMI); QoL scores. A control group of 50 healthy children was used.
Results: 42 type III AE (3 long-gap and 1 VACTER association). Median BMI was 18,72 (SD 3,38) (range: 30,52-12,80). In 22 pts BMI < 18,5. 19 pts were positive for dysphagia (EAT-10 score > = 3). A correlation was found between dysphagia and low BMI (Pearson 0,37). Dysphagia and low BMI were more diffuse in the younger population, while decreased in group B. 15 pts treated in their life for GERD (8 with medical therapy; 7 fundoplication). GerdQ test data showed only 4 pts with score > 6. GERD and dysphagia: 11 pts with GERD presented EAT-10 test > 3 (Pearson value confirmed this correlation: 0,59). Respiratory pathologies: 26 pts with positive anamnesis for chronic pulmonary affections (recurrent bronchitis in 21 pts; chronic cough in 15; the association of both in 12; 11 pts with asthma). PedsQL 4.0 median value was 15,4 (SD 10,1), control group value was 15,6 (SD 7,6); difference between the 2 groups was not statistically significant (p-value: 0,11). Correlation test for comparing high value of PedsQL and long-term complication in AE: the strongest association was with the dysphagia (Pearson: 0,55).
Conclusions: Dysphagia resulted the most disabling symptom in group A but swallowing function slightly improved with the growth. Generally, AE seems not heavily influence patients' QoL.
